All of which makes me wonder if Leon had more to do with the invention of the Acme namespace than Damian says above.

Not as far as I know (though, of course, he may well have been mind-controlling me without my knowledge). I actually wrote to Leon to apologize for having chosen "Acme" and to ensure he was okay with that. He was, as always, extremely gracious and bestowed his most aranciate blessing on the choice.
